 * Elgg radio input

 * @uses $vars['value']    The current value, if any
 * @uses $vars['name']     The name of the input field
 * @uses $vars['options']  An array of strings representing the options for the

 * @uses $vars['class']    Additional class of the list. Optional.
 * @uses $vars['align']    'horizontal' or 'vertical' Default: 'vertical'
